IMPROVEMENT lN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 194,653, dated August 28, 1877; application filed May 29, 1877.

To all whom it may concern:

Be it known that 1, JAMES A. GEocKER, of Providence, in the county of Povidence and State of Rhode Island, have invented a new and useful Improvement in Breech-Loading Guns, of which the following is a specification Thenature of my invention consists in combining with a double-barreled gun revolving charge-chambers, said chambers being so arranged and connected with guard and intermediate operating mechanism, that a single movement of the guard brings a new pair of charge-chambers in line with the pair of barrels. My invention also consists in certain details of construction, which may be best understood by reference to the drawings.

Figure 1 is a view showing the barrels and charge-chamber in elevation, also the other parts in section and elevation. Fig. 2 is a view showing the rear end of the chargechambers, the crown-ratchet and pawl for revolving the same, also part of the guard and clamping device. Fig. 3 is a vertical longi: tudinal section through the charge-chamber and adjacent parts. Figs. 4 and 5 are details relating to the chamber-locking device.

A A, Fig. 1, represent two barrels of a double-barreled gun or pistol. These, together with the stock, triggers, and hammers, may be made in any desired style and manner, and need not be further described.

The charge-chambers l) D E E, Fig. 2, are formed in the revolving block B, Figs. '1, 2, and 3. This revolving block is hung on the spindle G, and has attached to its rear end acrown-ratchet, F. H H is the guard, which is hung on a pivot, H in common with the two hammers K K. This guard when thrown out throws up the pawl F which is connected to it by the pin F and thus acting on the crown-ratchet F causes the charge-chamber block B to revolve through one half-revolution, the pawl F being held against the ratchet by the spring F, Fig. 1. This movement of the guard also serves to cook the hammers, which it does by coming in contact with the shoulders k h, Fig. 1, of the hammers, and thus forcing them back.

L ;L, Figs. 1 and 3, is a bent rod, which Serves to lock the charge-chamber block B, the point L entering a recess made in the block B. This'rod is thrown so as to engage with the recess by the spring L, which is disengaged from the block B by a switch-cam,

H Figs. 5 and 3, formed in the guard H,

which acts in the folowing manner: The bent rod L terminates in a swinging switch, L pivoted to it at L and held in line by a spring, L Fig. 4, so that when the guard H H is thrown down, the switch-cam El comes in contact with L and forces L and L forward, so that the point L is disengaged from the charge-chamber block B, thus leaving the block free to be revolved by the pawl F.

But when the guard H H is brought back the point of the switch-cam H throws the switch L aside, and thus fails to act on the locking device L U.

M, Fig. 3, is afriction block placed atthe end of the charge-chamber block B, and is pressed\ upon by a point, H, of the guard H B, when said guard is in normal position. As soon as the guard is moved in the slightest, the point H frees M from pressure, and thus leaves the block f'ree. The function of this frictionblock M is to force the charge-chamber block B hard up against the ends of the barrels, and thus prevent escape of gas.

Having now described the construction and operation of my invention, what I desire to secure by Letters Patent isl. The combination of the double barrel A A, and the charge chamber B, with the crown-ratchet F, the pawl F and the guard H H, all operating together, substantially as described, and for the purpose set forth.

2. The combination of the charge-chamber B, the bent rod L L and the guard H H, provided with the cam H substantially as described, and for the purpose set forth.

3 The combination of the charge chamber B and the friction-block M with the point H on guard H H, all operating together, substantially as described, and for the purpose set forth.
